!Friendica Support Is it possible to have posts show in a lemmy community? e.g. is it enough to use !keyword to have this post show in lemmy community !keyword ?

If not, what would be needed to cover this? I lack so much knowledge about #activitypub and federation that I am unsure if this question is smart or stupid, but dipping my toes in lemmy waters, it is a question that has been spinning in my head.
